Soon-to-be-40 Fergie says she and Prince Andrew are “the happiest divorced couple in the world” – despite the fact she’s still openly snubbed by her ex’s royal father, Philip, and brother, Charles.

But there’s one thing gnawing at the plucky Duchess of York.

She wishes her kids, Beatrice, 11, and Eugenie, 9, could see more of their cousins – Princes William and Harry – “because they get on so well,” she says in today’s Mirror of London.

“Beatrice and Eugenie were very close to William and Harry,” she says. “We’d all meet up when [Princess] Diana was alive and have great fun together.”

Now, the princes’ dad – heir-to-the-throne Charles – does not approve, she claims.

“He doesn’t have time for me, and that’s fine. It’s his decision,” she says. “I wish life wasn’t like it was with him, because I’ve always adored him.”

The flame-haired Sarah Ferguson, who turns 40 on Friday, says she’s amused everyone wants her and Prince Andrew to get back together. They still live in the same mansion near London with their two girls.
